ObjectiveTo investigate the therapeutic effects, safety of pneumatic lithotripsy and 2 μm laser via transurethral ureteroscope for ureteral calculi accompanied with granulation. Methods27 cases (30 sides) of ureteral calculi accompanied with granulation treated with 2 μm laser and pneumatic lithotripsy via ureteroscope were reviewed. Results28 sides were fragmented successfully in a single procedure. The operation time was 15～45 min (mean 25 min). The intraoperative blood loss was 3～15 ml (mean 5 ml). The postoperative hospitalization time was 3～7 d (mean 5.5 d). 1 upper ureteral stone was pushed back to the renal pelvis and extracorporeal shock wave lithotripsy was needed. The insertion of the ureteroscope was failed in 1 cases, who accepted open operation finally. Double-J tubes were pulled out in all the patients after 1 month, and 26 sides were stone-free. They were followed-up for 3～15 months (mean 8 months), no ureteral stenosis or urinary infection was found. Conclusion2 μm laser and pneumatic lithotripsy via ureteroscope is an effective and safe therapy for ureteral calculi with granulation, especially for those on middle or lower levels.

BackgroundMonocyte chemotactic protein-1 (MCP-1)plays an important role in the tumor,inflammation,diabetic retinopathy and other neovascular disease,but the expression and the role of MCP-1 in the oxygen induced retinopathy(OIR) model have rarely been reported. Objective This study was to investigate the expression of MCP-1 in the retina development of newborn mouse and in mouse models with OIR.Methods C57BL/6J newborn mice were divided into two groups and 60 mice in each group.Mice in OIR group were exposed to 75％ oxygen for 5 days and then to room air.All mice in normal control group exposed to room air only.Ten mice in each group were randomly chosen and sacrificed at postnatal 5,7,12,14,17,21 days.The expression of MCP-1 in mouse retina was detected with the method of immunohistoehemistry and reverse transcription polymerase chain reaction(RT-PCR).Results MCP-1 positive cells were seen in normal mouse retina.Up-regulation of MCP-1 positive cells was detected both in 12 days in normal control group and in 14 days in OIR group.MCP-1 mRNA was detected in mouse retina at 5 days,and a transient up-regulation of MCP-1 mRNA was observed in 12 days in normal control group.MCP-1 mRNA in OIR group significantly increased in 14 days in comparison with the normal control group( P =0.028,P =0.001 ). Conclusions Expression of MCP-1 is detectable in whole retinal development procession of mice.A transient up-regulation of MCP-1 expression is detected in the critical period of retinal vascular development in mice models with OIR,which is closely related to the retinal vascular development and progression of retinal new vessels.

Objective To improve the understand of the clinical characteristics of mycosis fungoides and provide guidance for the clinical work. Methods The clinical data of 21 patients with mycosis fungoides in our hospital were retrospectively analyzed including the ages at diagnosis, clinicopatholagic characteristics of skin lesions, systemic manifestation, misdiagnosis and treatment of these patients. Results The mean age was (57.3±2.31) years at the diagnosis. Most patients were at the stage of plaques. Clinical manifestations included generalized lesions (52.4 %) and itchy (66.7 %). Epidermotropism (66.7 %) and pautriers microabscesses(57.1%) were common histopathologic features. Previous misdiaguosis rate was 66.7 %. Skin targeted therapies and biologic therapies were effective approaches to relieve the skin rash at early stage, and combined chemotherapy was typically applied in more advanced cases. Conclusion Mycosis fungoides has various clinical characteristics and careful differential diagnosis should be made in clinical practice.

Objective To investigate the therapeutic effects, safety of ureteral calculus accom panied with granulation treated with pneumatic lithotripsy and two-macron laser via transurethral uret eroscopic. Methods From June 2007 to March 2010, 38 cases of ureteral calculus accompanied with granulation were treated with 2 μm laser and pneumatic lithotripsy via ureteroscope. All the patients had middle to severe hydronephrosis. The granulation under the calculus was vaporized with the 2 μm laser, and then the ureteral stone was fragmented with pneumatic lithotripsy. The clinical datum,stone disintegration rate, lithagogue rate and complication were retrospectively analyzed. Results Among 38 cases of ureteral stones, rate of successful fragmentation in a single procedure was 92%(35/38). The operation time ranged from 15 to 45 min, mean (23.0±6.5)min. Estimated the intraoperative blood loss was (7.0±4.5)ml. The postoperative hospitalization time was (5.2±0.6)d. Two upper ureteral stones were pushed back to the renal pelvis and a conversion to extracorporeal shock wave lithotripsy (ESWL) was needed. The insertion of the ureteroscope was failed in 1 case who was accepted open operation finally. Among the 37 cases treated via ureteroscopy, stone clearance rate was about 86% after operation 1 month. Follow-up examinations for 3-15 months (mean 8 months)showed no ureteral stenosis or urinary infection. Conclusion 2 μm laser and pneumatic lithotripsyvia ureteroscope could be a highly effective and safe therapy for treatment of ureteral stone with granulation.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

To study the effect of cholesterol and 25-OH-cholesterol on cholesterol metabolism in HepG2 cells and the effect of coptisine (Cop) extracted from Coptidis Rhizoma (CR) in reducing and regulating cholesterol. In this study, TC, TG, LDL-c and HDL-c were measured by biochemical analysis; mRNA and protein expressions of LDLR, HMGCR and CYP7A1 were detected by qRT-PCR and Western blot. According to the results, cholesterol and 25-OH-cholesterol inducing could decrease in mRNA and protein expressions of LDLR and CYP7A1, so as to increase TC and LDL-c contents. However, Cop could up-regulate mRNA and protein expressions of LDLR and CYP7A1 and down-regulate that of HMGCR, so as to reduce TC and LDL-c levels. These findings suggested that Cop has potential pharmacological activity for reducing cholesterol, and may reduce cholesterol by regulating mRNA and protein expressions of key genes involved in cholesterol metabolism, such as LDLR, CYP7A1 and HMGCR. This study laid a firm theoretical foundation for developing new natural drugs with the cholesterol-lowering activity.

OBJECTIVETo observe the clinical effect of low-dose once-daily tadalafil combined with Shuganyiyang Capsules in the treatment of mild-to-moderate erectile dysfunction (ED).

METHODSNinety patients with mild-to-moderate ED were equally randomized to groups A, B and C to receive Shuganyiyang Capsules, tadalafil, and tadalafil + Shuganyiyang Capsules, respectively. The scores of the patients on IIEF-5 and SF-PAIRS (15-Item Short Form of Psychological Interpersonal Relationship Scales) were recorded before and at 1 and 3 months after treatment.

RESULTSThe IIEF-5 scores of groups A, B and C were 10.13 +/- 1.55, 11.00 + 1.60 and 10.73 +/- 1.91 before treatment, and 13.77 +/- 2.11, 17.77 +/- 2.13 and 17.17 +/- 3.84 at 1 month after treatment, significantly higher in B and C than in A (P <0. 001) , but with no remarkable difference between B and C (P =0. 411). At 3 months after treatment, the IIEF-5 scores were 15.77 +/- 2.05, 18.07 +/- 2.24 and 19.37 +/- 3.76 in the three groups, dramatically higher in B and C than in A (P <0.001) as well as in C than in B (P<0.05). The scores on sexual self-confidence, sexual spontaneity and time concerns in SF-PAIRS were 3.90 +/-0.80, 8.67 +/- 1.94 and 14.43 +/- 1.92 before medication, 5.83 +/- 1.02, 9.90 +/- 1.75 and 11.17 +/- 1.68 at 1 month and 6.73 +/- 0.98, 11.07 +/- 2.08 and 10.67 +/-1.60 at 3 months after medication in group A; 4.17 +/- 0.87, 9.37 +/-1.43 and 14.47 +/-1.57 before medication, 6.47 +/-0.78, 10.83 +/- 2.18 and 10.20 +/-1.56 at 1 month and 6.83 +/-0.91, 11.30 +/- 1.88 and 9.47 +/- 1.57 at 3 months in group B; and 4.23 +/-0. 94, 9.50 +/- 1.89 and 14.67 +/- 2.91 before medication, 8.03 +/- 1.67, 13.43 +/-1.10 and 9.70 +/-1.21 at 1 month and 8.93 +/- 1.78, 14.70 +/- 1.26 and 8. 87 +/- 0. 97 at 3 months in group C. Compared with the baseline, the SF-PAIRS scores of the three groups were all significantly improved after treatment (P <0. 05) , and markedly higher in C than in the other two groups (P <0.05).

CONCLUSIONLow-dose once-daily tadalafil combined with Shuganyiyang Capsules is obviously effective in the treatment of mild-to-moderate ED, which not only improves the patients'erectile function, sexual self-confidence and sexual spontaneity, but also reduces their time concerns.
